A minimum-energy ballistic arc covering 750 km needs roughly 2.64 km/s at burnout and peaks near 181 km, by some quick napkin math, which puts Rook well above the 100 km Kármán line into space. The ballistic coast alone accounts for about six-to-seven minutes, leaving around eight of the claimed 15 minutes for boost, reentry, and landing. A 40-foot ISO container offers about 12.03 m of internal length and 2.35 m of width, capping the vehicle's dimensions. Rocket Lab's Electron stands 18 m tall and delivers about 300 kg to low Earth orbit.

The Air Force Research Laboratory made Rocket Cargo a Vanguard program in June 2021 and awarded SpaceX $102 million in January 2022 to work on the concept with Starship. Starship flew its 13th test on July 24, with the upper stage later splashing down in the Indian Ocean.

The Air Force renamed the effort Point-to-Point Delivery in its fiscal year 2025 budget request and asked for $4 million. A Johnston Atoll environmental review covering up to 10 reentry vehicle landings a year was suspended in July 2025, and Rocket Lab's AFRL reentry demonstration on Neutron hasn't flown yet. The Navy's answer to the same forward-supply problem is 3D printing spare parts at the deployment site .

Co-founder Jacob Balaj previously worked at Masten Space Systems, which ran more than 600 vertical takeoff and landing flights over 18 years and was developing its Xogdor vehicle for point-to-point payload transport when it filed for Chapter 11 in July 2022. Astrobotic bought the assets for $4.5 million that September.

Key considerations

  • Investor positioning can change fast
  • Volatility remains possible near catalysts
  • Macro rates and liquidity can dominate flows
